More isn’t necessarily better
Prescription retinoids are among the most extensively studied topical ingredients for the skin. They can improve the appearance of fine lines, pigmentation and skin texture and influence processes involved in collagen production.
But there is an important distinction between using an effective prescription retinoid and using the highest concentration available.
Higher strength tretinoin does not automatically translate into proportionally better anti-ageing results.
In fact, for many people whose primary goal is improving the signs of ageing, a lower concentration may provide meaningful benefits while being considerably easier to tolerate.
And tolerability matters enormously, because what use is a stronger retinoid if your skin becomes so irritated that you can only use it occasionally or you stop using it altogether?
Your skin barrier matters
One of the most common mistakes I see is assuming that redness, peeling and irritation are evidence that a prescription retinoid is “working harder”.
They’re not something you need to endure indefinitely in pursuit of better results.
Increasing the strength can increase the likelihood of irritation in some people. This can manifest as dryness, tightness, peeling, burning or persistent sensitivity.
Repeated irritation can also disrupt the skin barrier, leaving skin uncomfortable and less resilient and open to inflammation, dermatitis and other skin conditions.
A healthy skin barrier is fundamental to good skin. It helps maintain hydration and provides protection from environmental irritants.
So when we are thinking about long-term skin health, more irritation isn’t the goal.
Please stop trying to win the retinoid ladder
We often assume that moving from one concentration to the next means they are progressing. But prescription skincare isn’t a competition, and there is no prize for reaching 0.1%.
For some patients, a higher concentration may be clinically appropriate. For others, particularly when the goal is long-term management of ageing, a lower concentration may offer a very good balance between effectiveness and tolerability.
The better question isn’t:
“What is the strongest concentration I can use?”
It is:
“What concentration can I use consistently, comfortably and appropriately for my skin?”
That is a much more useful way to think about prescription retinoid treatment.
Think long term
If your skin is healthy, calm and responding well to a lower-strength prescription retinoid, don’t assume you need to move up simply because a stronger concentration exists.
The best prescription retinoid isn’t necessarily the strongest one. It is the one that is appropriate for your skin, your goals and your ability to use it consistently.
